Sewage at McDonald's

Inspectors also closed a McDonald's on 6228 Baltimore Ave. in Riverdale, MD.

Prince George's County Health officials say a grease overflow created a sewage backup at a drain in the parking lot.

"Potential for human contact with raw sewage and the potential in a food facility to actually contaminate the food," said Susan Thweatt Prince George's Co. Food Protection.

"My team was proactively working on a resolution for the equipment malfunction at the time when a customer also brought it to our attention," said Luis Gavignano, McDonald's Owner/Operator. "Providing my customers with a welcoming restaurant experience is always a top priority."

District inspectors ordered food operations closed at Malcolm Liquors on 3845 Minnesota Ave NE after finding mouse droppings two inspections in a row.
